It may be that you are having difficulty adjusting to a new living situation. You cannot overlook the fact the you recently left high school and began college. You’ve essentially only been in your new living situation for a few months. It takes time to make new friends.
I am not surprised that you are barely communicating with your high school friends. Often, high school friendships are based on convenience. In other words, when it is convenient to be friends ( i.e. because you’re attending the same school or living in the same neighborhood), the friendship flourishes. Friendships based on convenience often dissolve once the “friends” no longer see each other on a regular basis.
Many people feel lonely and even depressed when they leave their family and begin college. To answer your question directly, yes, many people feel the same way you do when they leave home. Adjusting to a new living situation can be difficult. It is normal to feel the way that you do.
I would recommend seeing a mental health professional. Utilize the counseling center services on campus. Meeting with a mental health professional could provide an objective opinion about your situation and provide much-needed support during this difficult time. In addition, your college counseling center may have support groups for students having similar readjustment difficulties. Please take care.
